Coordination and how to distinguish categories

Abstract

In this paper we have presented a detailed treatment of key problems in the syntax of coordination in English which goes well beyond previous treatments in the breadth of its coverage. The separation of immediate dominance rules from linear precedence rules had played an essential role in our analysis. It is this aspect of Generalized Phrase Structure Grammar that allows the full range of conjunctions in English to be treated in a unified manner using a small set of constructs. This same factoring of dominance and ordering information is what allows us to account for such problems as the peculiar properties of the coordination of embedded clauses and NPs, as we have shown. In addition, it is the interplay of various independently motivated principles in GPSG, such as the Head Feature Convention and the Foot Feature Principle, that enable one to derive, rather than stipulate, a solution to such long-standing problems as the facts commonly discussed in terms of the Coordinate Structure Constraint and the Across-the-Board Convention. Over twenty years ago, the syntax of coordination was a key topic in the discussions that led to the widespread acceptance of transformational grammar. It is curious, then, that even today no version of transformational grammar has succeeded in explaining, and often not even in describing, well-known and very basic facts about coordination (e.g., the fact that arbitrary tensed VPs can coordinate with each other). Moreover, the various instances of coordination of unlike categories, which we have provided an account of without appeal to any ancillary devices or ad hoc principles, have received no serious analysis within the transformational tradition. Of course, much remains to be done on the grammar of coordinate constructions. Among the problems we have addressed insufficiently or not at all are the precise formulation of the syntax and semantics of non-constituent ellipsis, the treatment of ‘right node raising’ constructions, and the semantic peculiarities of N1-coordination discussed by Bergmann (1982). Nevertheless, the present paper improves on earlier generative treatments of coordination by broadening the coverage while at the same time stipulating less.
